I have created a banner rotation script (i know your thinking oh no not another one) well i think the one i have made is quite good actually here are the features

Tracks pageviews / stats for unlimited sites Tracks pageviews / stats for unlimited advertisers Show both total and daily pageviews / clicks for advertisers and sites Login script for your advertisers (to view there stats) Login script for sites (to view there stats) IP checking so it only records 1 click per banner each day for that IP address sites expire after so many pageviews (then the get put into a expired file incase the want to buy more page views )

There are soo many of them out there your right, and one called webadverts is free, and has all of the same features, I also made my own however because I hated webadvert's administration panel. Also, I think if you want to be competitive, you'll definatly have to give a demo, and check out what the other programmers are selling theres for, onlinearts.com I think ..., anyway, they have one that doesn't do as much as yours I believe and they want $200 for it. So I think $60 is a good deal in that aspect.

i was thinking that i will release a FREE version of it as well with some of the admin functions disabled and then the script giving me 10% of the users ad space on there site then when they upgrade to the full version $60 it will have all the features enabled and my banner removed.

Also i am going to add another option so you can target ads to just 1 site
